SIGNAL MEANS FOR HAT FORMERS.

Application filed. Marnie, 1927. Serial No. 172,890.

This invention relates tosignal means for bat formers, the general object of theinvention being to provide means for notifying the operator when a sufficient amount of material has been placed on the forming cone, thus eliminating guesswork on the part of the operator and making it possible to produce hats of uniform weight.

A further object of the invention is to provide means for adjusting the signal op erating means so that such means'can be adjusted according to the weights of the hats to be produced. 1

A still further object of the invention is to provide means for readily resetting the signal actuating means after the hats have been removed from the former and material for forming another pair of hats is to be wrapped on the cone.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claims.

In describing my invention in detail, reference will be had to the accompanying drawings wherein likecharacters denote like or corresponding parts throughout the-sew eral views, and in which Figure 1 is a view showing'portions' of the hat forming machine with the invention in use thereon.

Figure 2 is an enlarged elevation of the invention.

Figure 5 is a plan view thereof.

Figure 6 is a detail view showing the pawl engaging the toothed wheel. i

As is well known, the hat forming material or webbing is taken from a carding machine and is wrapped upon a former which is .of double cone shape so that by dividing the material wrapped upon the former at the center thereof, two hatsare produced which are of conical shape and then these hats are shaped in other machines. Hereto fore, the operator had to guess at the amount of material wound upon the double cone and if there was not enough material wrapped upon the cone or too much, then the hats would have to be destroyed and the material passed through the carding maformer and the other the material forming chine again. This notonly wastes timeand labor but after the material has been run through the carding machine several times, it will produce inferior hats; 1337 my inven tlon, a s1gnal is given as soon as-sufiicient material has been placed on the double cone so that the operator can take the cone with the material thereon from the machine and the pair of hats produced will have the weight desired.

In carrying out my invention, I provide a frame 1 which is suitably attached to the frame 2 which carries the conical rollers 3 which support the double conical former 4 upon which the webbing A is wrappedfor producing a pair of hats. A shaft 5 is supported by theuprights 6' forming portions of said frame and a sleeve 7 or hollow shaft is rotatably mounted on the shaft 5. An L-shaped arm 8 is formed with or connected to saidhollow'shaft? and a weight 9is carried the outer end of said arm. A sectional arm 10 is also formed with or attached to the hollow shaft 7, this arm being opposite the short part of the L-shaped arm 8 and the section 10 is connected with the other section of the arm 10 by the bolt 11 so that the section 10 can be adjusted on the other section. The section 10 has a head 12 at its outer end which is perforatedto receive the shanks 13 of the wings 14. The shanks are adjustably held inthe perforations by theset screws 15. These wings are adapted to be set so that one ofthem'will engage the material forming one-hat on the the other hat, as shown in Figure 1.

A toothed wheel 16is rotatably mounted on one end of the shaft 5 and this wheel carprojection 18 engaging the arm 10, will swing the same upwardly to a position where the wings 14 will be out ofcontact with the hats on the former and the weight 9 will .be engaging the operating part of a bell 21 or other alarm. A lever 22 is pivoted to an upright 23 forming part of the frame and the front end of said lever is shaped to provide a pawl 24: which engages the toothed wheel and prevents the same from being moved by the spring 19. The rear end of the lever is formed with an enlarged eye forming part 25 in which projects a pin 26 carried by an arm 27 which is adjustably connected to the Weight carrying arm 8 by the bolt and its wing nut 28.

A wheel 29 is rotatably mounted on the shaft 5 adjacent the end which is opposite to that on which the wheel 16 is mounted and said wheel 29 has an arm 30 thereon which carries a pin 31 extending under the arm 8l A coiled spring 32 is fastened to the frame 1 and to a projection on the wheel 29 andacts to holdthe wheel with the pin 31 in its lowest position. A wire or cable 33 is fastened toa projection on thewh'eel 29 and passes through a flexible conduit 34 fastened to the frame 2 and said cable 33 has a handle 35 at its outer end which is so positioned that the operator standing near the former cone can grasp the handle whenever necessary.

Astop pin 36 is carried by a slotted member 37'which is adjustably fastened to the front part of the frame 1 by the bolt 38 which passes through the slot in the member 37. The pin acts as a rest for the arm 10=to, space the wings from the formervcone, and 'by adjusting the member 37 on the frame, the wings can be placed the desired distance from the cone.

.From the foregoing it will be seen that after the pin-36 has been properly positioned toshold the: wings a certain distance from the former cone and the hat forming machine has been started up, after a certain amount of material has been Wrapped on the former cone, the material will contact with the wings and as more material is wrapped on the former cone, the wings will be pushed rearwardly and thus the arm 10 will be raised and the weighted arm 8 will be low- ;ered. Finally, the: pin 26 will strike the lower wall of the eye 25 and thus rock the lever 22 so as to move the pawl 24 out of engagement with the toothed wheel. This willpermit the toothed wheel to be partly rotated by the contraction of the spring. 19

and as the wheel moves, the pin 18 thereon will strike the arm 10 and move the parts until the wings are spaced a considerable distance from thehats on the former cone and the weight will strike the bell and cause the same to sound. which will notify the operator that sufficient material has been placed on the former cone to form two hats ofthe proper size. The operator then removes the hats from the former cone. This can be done withoutinterference on the part of. the wings as they have been moved away from the cone. When another pair of hats is 'ijo'lvc produced. the operator pulls upon the cable by means of the handle 35 so as to rotate the wheel 29 against the tension of the spring 32, which will cause the pin 31, carried by the wheel, to engage the arm 8 and lift the same which will return the parts to their first position. As the parts are raised, the pin 26 will pass upwardly in the eye so that the lever can return to its normal position and engage a tooth of the wheel 16 which has also been moved through means of the pressure exerted upon the pin 18'by the downwardly moving arm 10, which will stretch the spring. 19 and thus the parts will be held in this position by the pawl engaging a tooth of the wheel 16. The wheel 26 is then returned to its normal position by means of the spring 32. The parts are then set ready to he again acted on by the pressure of the material being wrapped upon the former cone.

This invention will notify the operator as soon as the proper amount of material has been placed on the former cone to produce a pair of hats the material of which is of the desired thickness to form hats of a certain weight and by adjusting the stop pin 36, the device can be set to operate to produce hats of any desired weight.

It is thought from the foregoing description that the advantages and novel features of my invention will be readily apparent.
